Estado: AnalizadaMedia (6.5)—

A vulnerability in the web-based management interface of Cisco IoT Field Network Director could allow an authenticated, remote attacker with low privileges to retrieve files that they do not have permission to access.

This vulnerability is due to insufficient file access checks. An attacker could exploit this vulnerability by submitting crafted input in the web-based management interface. A successful exploit could allow the attacker to read files that they are not authorized to access.
